Python Remove Non Printable Characters

What are Non-Printable Characters?

When working with strings in Python, you may encounter non-printable characters that can cause issues with your code. Non-printable characters are characters that are not visible on the screen, such as tabs, newlines, and carriage returns. These characters can be problematic when trying to process or manipulate strings, as they can affect the output or behavior of your program.

Non-printable characters can appear in strings for a variety of reasons, including user input, file imports, or network transmissions. For example, if a user copies and pastes text from a word processor into a text field, the text may include non-printable characters such as tabs or newlines. Similarly, if you import data from a file, the file may contain non-printable characters that need to be removed.

Removing Non-Printable Characters with Python

What are Non-Printable Characters? Non-printable characters are characters that have an ASCII value between 0 and 31, or 127. These characters are not visible on the screen and can include tabs, newlines, carriage returns, and other control characters. In Python, you can use the ord() function to get the ASCII value of a character, and the chr() function to get the character represented by a specific ASCII value.

Removing Non-Printable Characters with Python To remove non-printable characters from a string in Python, you can use a combination of the join() and isprintable() functions. The isprintable() function returns True if a character is printable, and False otherwise. You can use this function to filter out non-printable characters from a string, and then join the remaining characters back together into a new string. For example: new_string = ''.join(c for c in old_string if c.isprintable()). This code will create a new string that includes only the printable characters from the original string.
